The large-scale data stream problem refers to high-speed information flow which cannot be processed in scalable manner under a traditional computing platform. This problem also imposes expensive ...labelling cost making the deployment of fully supervised algorithms unfeasible. On the other hand, the problem of semi-supervised large-scale data streams is little explored in the literature because most works are designed in the traditional single-node computing environments while also being fully supervised approaches. This paper offers Weakly Supervised Scalable Teacher Forcing Network (WeScatterNet) to cope with the scarcity of labelled samples and the large-scale data streams simultaneously. WeScatterNet is crafted under distributed computing platform of Apache Spark with a data-free model fusion strategy for model compression after parallel computing stage. It features an open network structure to address the global and local drift problems while integrating a data augmentation, annotation and auto-correction (DA3) method for handling partially labelled data streams. The performance of WeScatterNet is numerically evaluated in the six large-scale data stream problems with only 25% label proportions. It shows highly competitive performance even if compared with fully supervised learners with 100% label proportions.
In the context of Natural Science lessons, students often lack critical thinking skills. To address this challenge, the researchers developed the “I Can Adapt” scientific module for students at SMP ...Negeri 10 Magelang. This study evaluates the module’s viability, efficacy, and practicality using a research and development (R&D) approach based on the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The expert validation process confirmed the module’s validity, with material experts rating it at 4.0 and teaching materials experts at 4.2. To assess efficacy, the researchers employed a one-group pretest-posttest design with paired sample t-test analysis. The results revealed a significant increase in critical thinking skills (p < 0.05), as indicated by a significance value of 0.00. The average N-Gain score of 0.83 falls within the high category. Furthermore, student questionnaires related to the RIAS-based science modules demonstrated a practicality level of 84.6%. Overall, the findings support the use of the “I Can Adapt” RIAS-based science module as an effective tool for enhancing critical thinking abilities.

Triangulasi digunakan dalam proses penilaian keabsahan data penelitian ini. Reduksi data, visualisasi data, dan pengambilan kesimpulan digunakan untuk menguji prosedur analitik data. Berdasarkan temuan penelitian, beberapa anak masih mengalami kesulitan dalam mengucapkan dan mengenali huruf b dan d, membaca kata yang memiliki imbuhan, dan memahami frasa sederhana. Temuan studi ini menunjukkan bahwa elemen internal, seperti tanda-tanda kelelahan dan tanda-tanda motivasi siswa untuk mengakses bahan bacaan, merupakan penyebab terjadinya tantangan membaca. Latar belakang dan kemahiran membaca adalah contoh faktor lingkungan eksternal. Guru juga telah melakukan berbagai peran dalam membantu siswa mengatasi tantangan membaca mereka, seperti pembawa pesan, fasilitator, perantara, penilai, administrator atau direktur, motivator, penyelenggara, atau inisiator.
Students as young generation and agent of change are required to be always active in academic and non-academic activities; therefore in the process, they will encounter various obstacles and ...obstacles. Not infrequently it makes them experience stress. The fact that students often do not know the situation that they are experiencing stress. So there is a need for a system to detect students stress levels to reduce the adverse impacts. With the development of Backpropagation method as a guided learning method combined using Depression Anxiety and Stress Scale 42 (DASS 42) as a scale to identify stress levels in students based on emotional, physical, and behavioural variables. It is expected to be a reference in helping students to detect the level of stress they are experiencing. Also, the use of Backpropagation method is used to see the level of accuracy of data in the system.
Climate change is a major concern. Climate change causes changes in the seasons and hydrological systems. Landslides are one of the most common hydrometeorological disasters in Indonesia. This study ...identifies indicators of economic and social vulnerability to the risk of landslides in the Tawangmangu and Kejajar sub-districts. The method used is scoring and weighting of each economic indicator namely the Gross Domestic Regional Product at Current Prices (PDRB ADHB) of the sub-district and the number of poor people, as well as social indicators used, including population growth rate, sex ratio, population density data, the number of children at risk, the number of elderly at risk which are analyzed using the SoVI index referring to the Regulation of the National Disaster Management Agency No. 2 Year 2012 and research conducted by Sulma, 2012 to determine the vulnerability of the two sub-districts to landslides. Tawangmangu and Kejajar sub-districts are classified as areas with moderate vulnerability, so the economic and social conditions of the Kejajar sub-district are more vulnerable to the risk of landslides. If a region has a high SoVI index due to landslides, it can affect agricultural productivity because landslides affect agricultural land. The government can use disaster studies as a basis for determining broader regional policies and accelerating regional economic recovery through the improvement of economic facilities and infrastructure in disaster-prone production sectors.
Attitude is one of the most prominent issues in bilingualism. It becomes crucial and interesting because it is related to how speakers preserve their language to avoid language attrition and to ...maintain their established language competence. This study investigates the attitudes of two Indonesian siblings, a 19-year old and a 24–year old, who migrated to Australia with their parents in 2002. This study looks into their attitudes towards their Indonesian L1 after living for 11 years in Australia. An interview was conducted along with a guided questionnaire with both participants. The results revealed that their attitudes toward their Indonesian L1 are different regardless of having had the same treatments from their parents. The younger sibling seems to be more reluctant to use his Indonesian L1 and now, he has difficulties in speaking in Indonesian. Accordingly, the possibility of his partial loss of his L1 was indicated. The results further show that their different attitudes are one of the factors that foster the language loss suffered by the younger participant, especially the loss of vocabulary knowledge. The study also found some demographic factors such as the age of onset and the level of education when he started studying at an Australian school that may have influenced the difficulties that the younger participant has with production of his L1.
Subzone Cimanuk sub-watershed upstream is playing an important role towards the conservation of water resources for the downstream subzone. To meet the needs of the community, drinking water for ...agricultural irrigation. However, the amount of land conversion causes the water system in the watershed disturbed. This study aimed to analyze the changes in land use in the watershed Cimanuk upstream and analyze changes in the carrying capacity of the water system upstream use Cimanuk geographic information systems. The analysis shows that it has increased there use of its land area cultivated by horticultural fields such as carrots, potatoes, and other crops. Food and agricultural land development in research, at least from 2005 to 2015, has an adverse impact on the functioning of the Sub-Basin Upstream Cimanuk characterized by decreasing the carrying capacity for water regulation. Or that the development of agricultural land in this area is actually very appropriate if only from the aspect of that is because of relatively fertile landforms (volcanic areas), but the development has destroyed sub-watershed function itself as a water catchment area.
The development of the world of digitization is so fast that changes in the education sector also have an effect on the growing learning model.
